Suitable material for the punches

Suitable material for the punches

(OP)
Hi,

I'm working in a perforation plant. We have some difficulties with the small dia (1.5 mm) punches. Material to be perforated is soft galvanised steel in 0.5 mm thickness.
I guess the material (HSS) and/or heat treatment (60 HRC) is not good enough for the punches.
Can you advise your experiences regarding this subject?

Thanks in advance.

Try Sverker 3

RE: Suitable material for the punches

Where are you purchasing your punches?

Are your punches coated?
